Aerodynamic challenges in span length of suspension bridges

Frontiers of Architecture and Civil Engineering in China, 2007
The potential requirement of extreme bridge spans is firstly discussed according to horizontal clearances for navigation and economical construction of deep-water foundation. To ensure the technological feasibility of suspension bridges with longer spans, the static estimation of feasible span length is then made based on current material strength and ...

On the Difference of Expected Lengths of Minimum Spanning Trees

Combinatorics, Probability and Computing, 2009
An exact formula for the expected length of the minimum spanning tree of a connected graph, with independent and identical edge distribution, is given, which generalizes Steele's formula in the uniform case. For a complete graph, the difference of expected lengths between exponential distribution, with rate one, and uniform distribution on the interval

Relating bending stiffness measurements across various free span lengths

TAPPI Journal, 2020
Bending stiffness should be an intrinsic property of a material, so it is puzzling that the TAPPI Standard Test Method T 836 “Bending stiffness, four point method” specifies span lengths when testing different types of corrugated fiberboard. These specified spans often limit the samples that can be measured with this method.

Optimal Simple Span Lengths for Flexible Guideways

Journal of Structural Engineering, 1984
In the design of elevated vehicle/guideway systems several parameters play important roles in the dynamic performance. The vehicle inertial and suspension properties, guideway mass per unit length, span length, structural damping characteristics and surface finish tolerances are important factors.

Engineering demand functions for RC medium length span bridges

Bulletin of Earthquake Engineering, 2014
The evolution of the seismic design philosophies and the strong correlation of some structural demands with damage, motivate the research community to improve the knowledge about the pier demands in bridges. The seismic demands can be determined by conducting non-linear time history analyses, however, the computational time required can be excessive ...

Allowable span length of submarine pipeline in shallow water

Marine Georesources & Geotechnology, 2017
AbstractBecause of the complex geological conditions of the seabed, submarine pipelines buried beneath the ocean floor become suspended over the seabed under the long-term scour of waves eroding the surrounding sediment. Further, most oil fields were built in offshore areas while the country was developing.

Constructing minimal spanning/Steiner trees with bounded path length

Integration, 1997
Summary: This paper presents an exact algorithm and two heuristics for solving the Bounded path length Minimal Spanning Tree (BMST) problem. The exact algorithm which is based on iterative negative-sum-exchanges(s) has polynomial space complexity and is hence more practical than the method presented by Gabow. The first heuristic method (BKRUS) is based

Optimum Spans' Lengths of Multi-span Reinforced Concrete Beams Under Dynamic Loading

In the design of continuous beams, say bridges, achieving an economical layout is one of the primary objectives, and requires simultaneous consideration of cost and layout variables. This study aims to figure out an explicit methodology for the optimum layout design of multi-span reinforced concrete beams under dynamic loadings in order to optimize the
